Description
本申请要求于2014年12月03日提交中国专利局、申请号为201410729759.3、发明名称为“一种电子终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及电子设备技术领域，特别涉及一种电子终端。
在电子设备技术领域，小型化的终端设备中，电子终端的散热性能是用户选择产品时考虑的一个重要因素。
由于小型化终端设备中电子终端的尺寸较小，具体包括壳体、安装于壳体内的电路板、安装于电路板上的散热块、安装于散热块以向散热块吹风的风扇；散热块上设有剖沟，风扇吹向散热块的风在经过散热块的剖沟后沿剖沟吹出。
但是，现有技术中，电子终端内没有设计风道，自散热块的剖沟吹出的热风大部分会直接进入风扇的进风口，从而再次吹向散热块，降低了散热块的散热效率，从而导致电子终端的散热效率较低。
发明内容
本发明提供了一种电子终端，该电子终端能够防止散热块散出的热空气再次进入到风扇的进风口，进而能够提高电子终端的散热效率。

所述挡风板安装于所述壳体内、且与所述散热风扇的外壳以及所述壳体内壁密封配合以将所述壳体内空间分隔为冷风入风腔室和散热腔室；所述电路板以及所述散热块位于所述散热腔室内；所述散热风扇的入风口与所述冷风入风腔室连通，出风口与所述散热腔室连通；
所述壳体上设有与所述冷风入风腔室连通的入风孔和与所述散热腔室连通的出风孔，所述入风孔设置于所述壳体的底侧，所述出风孔设置于所述壳体的顶侧。
结合上述第一方面，在第一种可能的实现方式中，壳体包括筒体、底板和顶板，所述挡风板与所述筒体以及所述底板密封配合，所述电路板与所述筒体的轴心线平行地设置于所述筒体内。
结合上述第一种可能的实现方式，在第二种可能的实现方式中，所述入风孔为：
所述底板上设有的多个与所述冷风入风腔室连通的通孔；或者，
所述底板与所述筒体之间形成的透风间隙。
结合上述第一种可能的实现方式，在第三种可能的实现方式中，当所述入风孔为所述底板上设有的多个与所述冷风入风腔室连通的通孔时，所述底板与所述冷风入风腔室相对的部位具有网板结构，具有网板结构的底板上的网孔形成所述通孔。
结合上述第一种可能的实现方式，在第四种可能的实现方式中，所述出风孔为：
所述顶板设有的多个与所述散热腔室连通的通孔；或者，
所述顶板与所述筒体之间形成的与散热腔室连通的透风间隙。
结合上述第一种可能的实现方式，在第五种可能的实现方式中，所述挡风板包括：
沿筒体轴心线方向延伸、且位于所述散热风扇两侧的两个竖挡风板；
沿垂直于所述筒体轴心线方向延伸、且位于所述散热风扇朝向顶板一侧的第一横挡风板；
沿垂直于所述筒体轴心线方向延伸、且位于所述散热风扇朝向底板一侧的第二横挡风板。
结合上述第五种可能的实现方式，在第六种可能的实现方式中，所述底板上设有向顶板方向凸起的螺丝柱，所述筒体内壁设有沿筒体轴心线方向延伸的加强筋；其中：
每一个所述竖挡风板为一个所述螺丝柱外周面上设置的筋板；
所述第一横挡风板设有与所述筒体内加强筋滑动密封的滑槽；所述第一横挡风板与所述筒体铆接；所述第一横挡风板朝向顶板的一面与所述加强筋设有的朝向所述底板的压面相抵；所述第一横挡风板朝向底板的一面与所述螺丝柱设有的朝向所述顶板的支撑面相抵；

上述第一方面提供的电子终端中，挡风板将壳体内空间分割为散热腔室和冷风入风腔室，散热风扇的入风口与冷风入风腔室连通，因此，在电子终端设置的散热风扇工作时，冷空气自壳体底侧的入风孔进入冷风入风腔室内，散热风扇将冷风入风腔室内的冷空气吹向散热块对散热块进行散热；由于散热块位于散热腔室内，散热风扇吹入的冷空气与散热块进行热交换后变为热空气，热空气自设置于壳体顶侧、且与散热腔室连通的出风孔吹出壳体。由于散热腔室与冷风入风腔室之间通过挡风板隔离，散热腔室内的热空气无法进入到冷风入风腔室内，并且，冷风入风腔室内的冷空气自壳体底侧的入风孔进入，而散热腔室内的热空气自壳体顶部的出风孔吹出壳体，因此，热空气在吹出壳体后向上升，所以，散热腔室吹出的热空气无法自壳体底侧设置的入风孔进入冷风入风腔室内，因此，散热风扇吹向散热块的空气为冷空气，进而提高了电子终端的散热效率。

挡风板5安装于壳体内、且与散热风扇4的外壳以及壳体内壁密封配合以将壳体内空间分隔为冷风入风腔室和散热腔室；电路板7以及散热块6位于散热腔室内；散热风扇4的入风口与冷风入风腔室连通，出风口与散热腔室连通；
壳体上设有与冷风入风腔室连通的入风孔21和与散热腔室连通的出风孔13，入风孔21设置于壳体的底侧，出风孔13设置于壳体的顶侧，如图1和图2所示。
上述电子终端中，挡风板5将壳体内空间分割为散热腔室和冷风入风腔室，散热风扇4的入风口与冷风入风腔室连通，因此，在电子终端设置的散热风扇4工作时，如图1、图2和图4所示，冷空气自壳体底侧的入风孔21进入冷风入风腔室内，散热风扇4将冷风入风腔室内的冷空气吹向散热块6对散热块6进行散热；由于散热块6位于散热腔室内，散热风扇4吹入的冷空气与散热块6进行热交换后变为热空气，热空气自设置于壳体顶侧、且与散热腔室连通的出风孔13吹出壳体。由于散热腔室与冷风入风腔室之间通过挡风板5隔离，散热腔室内的热空气无法进入到冷风入风腔室内，并且，冷风入风腔室内的冷空气自壳体底侧的入风孔21进入，而散热腔室内的热空气自壳体顶部的出风孔13吹出壳体，因此，热空气在吹出壳体后向上升，所以，散热腔室吹出的热空气无法自壳体底侧设置的入风孔21进入冷风入风腔室内，因此，散热风扇4吹向散热块6的空气为冷空气，进而提高了电子终端的散热效率。

如图6所示，第一横挡风板51设有与筒体1内加强筋11滑动密封的滑槽；第一横挡风板51与筒体1铆接，如图6中所示，第一横挡风板51通过热熔方式形成的铆接点12与筒体1铆接；第一横挡风板51朝向顶板3的一面与加强筋11设有的朝向底板2的压面相抵，第一横挡风板51朝向底板2的一面与螺丝柱22以及螺丝柱23设有的朝向顶板3的支撑面相抵(图中未示出)；上述第一横挡风板51能够通过筒体1以及底板
2上的结构实现定位；
如图2和图4所示，上述第二横挡风板53设置于底板2，当然，上述第二横挡风板53可以与底板2具有一体式结构。
具体地，在上述各实施方式的基础上，壳体中，沿垂直于筒体1轴心线方向，筒体1的横截面外边缘的形状为圆形、方形、或菱形以及其它类似筒类形状。
